WebAug 23, 2024 · Percutaneous coronary intervention (PCI) with stent placement is a standard treatment for coronary artery disease (CAD). Despite all medical advances, restenosis remains a challenging clinical problem. However, the molecular and biochemical pathways of restenotic process are not fully understood yet. Furthermore, as restenosis … WebA 2010 study in India comparing coronary drug-eluting stents (DES) with coronary bare-metal stents (BMS) reported that restenosis developed in 23.1% of DES patients vs 48.8% in BMS patients, and female sex was found to be a statistically significant risk factor for developing restenosis.

WebObjective: In-stent restenosis (ISR) is a fatal complication of percutaneous coronary intervention (PCI). An early predictive model with the medical history of patients, angiographic characteristics, inflammatory indicators and blood biochemical index is urgently needed to predict ISR events. We aim to establish a risk prediction model for ISR ... WebBecause of its antiproliferative effect on vascular smooth muscle cells, balloons and stents are coated with paclitaxel for use in coronary revascularization and prevention of in-stent restenosis (ISR). However, mechanisms underlying ISR are complicated. Platelet activation is one of the major causes of ISR after percutaneous coronary intervention.
